Hi there.
I'm very sorry your issue has sat here for so long without a response.
Us volunteers are a little on the burnt-out side right now! That's not an excuse, though, but let's see if we can make some progress, if you're still around after all this time...
Everyone has been very helpful in this thread. Much of what I would recommend, they have already recommended. Unfortunately, I don't have a Mac, so it's tough for me to help as much as I'd like here.
To be absolutely clear - there would never be a scenario in which uninstalling the game would void your license! So, don't worry about that.
Meanwhile, are you still having the issue? Generally, this issue has required a reinstall in the past, and yes, this means reinstalling 2.0.1 and then patching again.
Please let me know where things stand, so I can figure out where else I can be of assistance!
Steve
